Zakreśl literę A, B, C lub D.Body language is the way people reveal their thoughts and emotionssimply by moving their body in certain ways. More often than not, theydon’t even realise they are doing it. It could be the gestures a personmakes with their hands, the way they move their head or even how theyuse their eyes or mouth. In other words, people can give unspokensignals which communicate meaning just as much as words do.Psychologist Dr Kevin Lacey stresses the importance of bodylanguage. “In order to make a good impression, just saying the rightthing isn’t enough,” he says. “How we say it, and the body languagewe use, can be just as important.”So what does Dr Lacey suggest we do to improve the sort of message our bodylanguage is sending? “Firstly, when you sit opposite someone, don’t cross your arms orlegs,” he advises, “and if you are wearing a jacket, open it. Otherwise, your positionlooks ‘closed’ and people may easily think you have something to hide. An openposture, on the other hand, makes people think that you are being honest. If you wantto show you are interested in what someone is saying, you should lean forward withyour head slightly to one side. This suggests that you are paying attention to them.Making direct eye contact is usually a good idea too, although in some cultures, such asin some parts of Asia, it can be a sign of disrespect.” But it’s not just a question of giving out the right signals ourselves. It can also be very useful to understand someoneelse’s body language. If, for example, you want to know whether someone is telling the truth or not, there are a number of simple signs to look out for. “If someone’s eyes keep moving quickly around the room and they keep ontouching their face,” Dr Lacey explains, “there is a good chance the person is not being completely honest.” So the next time you meet someone new, why not follow Dr Lacey’s advice? Hopefully, body language will help youto trust and be trusted!1 Body language can show people’sA movements.B looks.C feelings.D understanding.2 Dr Lacey thinks that body language isA of hardly any importance.B more important than speech.C an important way of communicating.D less important than speech.3 Crossing your arms or legs suggests youA are feeling angry.B are not easily annoyed.C feel uncomfortable.D are keeping something back.4 Looking someone straight in the eyesA should not be done everywhere.B will gain you people’s respect.C is only acceptable in Asia.D shows that you are highly cultured.5 A sign that someone is lying is when theyA keep walking round the room.B don’t look at one thing for long.C keep looking at your face.D try to leave the room quickly.6 Dr Lacey believes that body languageA shows how others feel.B is tricky.C helps us communicate better.D cannot be trusted.
